What is the definition of a control valve attachment line? Which expert knows this? It needs to be based on some evidence. Thank you!
Put simply, if one of your control valves fails and needs to be repaired, how can it be repaired or inspected without a bypass line? For a professional explanation, look for some lecture materials or standard specifications on forums.
